see i drive a 1991 toyota pick up truck and everyone tells me make box in bed and cuts holes to my cab i cant do that ): hurting my baby plus i think it would look like crap , BTW i think there some speaker that can fit behind your seat if they fit behind mine and still drop a lot bass. personally i like kicker ive always used it and my kick 10" comps hit pretty nice and fit great in my truck amp is under my seat i am using 4 gauge wiring and 10 gauge sub speaker wire.
